XT Miniature Controls includes nonreversing
contactors, auxiliary contacts
and mini overload relays. A wide range
of applications is possible including small
electrical motors from fractional to 5 hp
(460 Vac) or up to 4 kW (400 Vac).
Due to its compact size, the XT line of mini
controls is best suited to be applied in light
duty loads such as hoisting, packaging,
material handling, heating, lighting and
automation systems. XT mini contactors
are a particularly compact, economic and
environmentally friendly solution wherever
control of small motors or loads is required.
Front mounted snap-on auxiliary contacts
for mini contactors are available with screw
terminals in a variety of contact
configurations. Auxiliary contact modules
are standard with interlocked opposing
contacts, except in the case of early make
or late-break contacts.
The XTOM overload relays are three-pole
electromechanical motor circuit-breakers
using bimetallic elements. They are suitable
for monitoring both DC and AC currents.
Type XTOM overload relays have been
designed to be fitted directly on to XTMC
contactors. In the event of overload
tripping, the auxiliary contacts change over
and disconnect the control voltage circuit
from the corresponding contactor relay,
and thus indirectly switch off the current
to the motor being monitored. The XTOM
relays are adjusted by means of a setting
wheel to suit the motor current rating.
